“…Guo et al (2015) presented an investigation on flexural-torsional buckling of T and I section beams and proposed fitting formulas to estimate the buckling capacities. Wang et al (2016) presented an investigation on the local buckling of I-section beams under concentrated loads and found that intermediate stiffeners and a thick web are helpful to increase the bearing capacity of I-section beams. Feng et al (2017) studied SHS/RHS beams with circular holes and compared the experimental results with the design results; the results found that the DSM approach provided relatively accurate predictions.…”

Aluminum alloy members of channel sections are widely used in lightweight structures, especially as pillars of curtain wall systems, and brace and chord members in roof trusses. This paper presents both experimental and numerical studies on the behavior of aluminum alloy channel section beams. In this study, a series of four-point bending tests under minor-axis and major-axis bending was carried out. The test specimens included plain and lipped channel sections of both 6063-T5 and 6061-T6 aluminum alloys. A finite element (FE) model of the channel section beam was developed by using the FE package ABAQUS. The ultimate bending resistances and failure modes of the FE model were compared with the results from the bending tests. The validated model was employed for the parametric study to generate numerical simulation results. A total of 55 new experimental and numerical beam results were compared with the predictions from existing aluminum alloy design specifications from America, Australia/New Zealand, Europe and China. Additionally, two commonly used design approachesthe Continuous Strength Method (CSM) and the Direct Strength Method (DSM)-were also applied to predict the bending capacities for comparisons. A modified DSM approach for aluminum alloy channel section beams is proposed herein. Finally, reliability analyses were conducted to evaluate the aforementioned design methods. The results show that in comparison with other considered design

Clad steel possesses benefits of the both component metals in terms of mechanical performance, corrosion resistance, sustainability and lower full lifecycle cost, etc. As a result, it has been more and more widely used in the petroleum, chemical, marine, shipbuilding and metallurgical industries, including stainless-clad steel and titanium clad steel. Such clad steel has also great potential for application in building and bridge structures. For better understanding material properties of such clad steel, a review of research progress available in the literature is conducted herein, as well as recent research undertaken by the authors’ group at Tsinghua University. It can be found that very limited research reported in the literature mainly concerns static material properties of the clad steel, and primary relations between clad ratio and strength are suggested. The authors carried out material tests on both titanium and stainless-clad steel plates, with different clad ratios being incorporated. For the stainless-clad steel tests, both material and butt welded connections are tested, and various elevated temperatures are considered. In addition, tension coupon tests under cyclic loadings are also briefly introduced herein. Primary constitutive relations developed by the authors are reviewed in this paper. All the research findings and proposed formulae may provide an essential basis for future structural analysis, and may promote its application in structural engineering.
